Here is the relevant section from the history documentation of the program:
Dec. 03/01: V.2.0 Release by Stefan Peichl: Better memory management saves precious 60KB! PALRUN now only uses 21KB of memory (was 81KB). New MINIPAL uses only 5KB of memory. MINIPAL as TSR takes 3KB of memory only. Support of 640x350 EGA and 800x600 SGA. HP95 Video mode is mapped to CGA. Support of tiny 6x8 font. Support of vertical output. Default screen mode changed to reverse VGA. HFN font size is reduced between 25% and 50%. Optional TSR functionality added. Optional detection of Alt-M as Menu key. Optional Windows awareness. Optional "fast scroll" for PE (i.e. no scroll) Reverse Video is now the default. Command line switches more intuitive now. ASCII character 127 is the EURO sign "€". 80186 opcodes used for speed reasons. Conditional assembly requires TASM. Bug fixes: - Rep Rule byte bug fixed. - Put & Get image bug fixed. - Plot Line rule bug fixed. - PE Cursor shape bug fixed. - Clip region support added.
All I can say is "WOW!" and a BIG THANK YOU, Stefan!
